application filed July 25,

To all whom it may concern:

Be it known that I, MAX KLEIN, a cltlzen of theUnited States, residing at Philadelphia, in the county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Lighting Fixtures, whereof the following is a specification, reference being had .to the accompanying drawing.

ly invention may be employed with particular advantage in ceiling fixtures for incandescent electric lamps, constructed and arranged to reflect the major portion of the light therefrom upon the ceiling, but permitting a minor portion thereof to be projected through a subjacent medium, preferably including glass in prismatic form.

In the form of my invention hereinafter described; the reflecting element aforesaid is conveniently upwardly and outwardly curvedlike the mouth of a trumpet and is so constructed and arranged with reference to the lamp which it incloses, as to not only project but widely diffuse the light therefrom upon the ceiling, and is made of cased glass, which is so far translucent as to display a color by light projected therethrough white light upon said the fixture is suspended. In that embodiment, the prismatic element aforesaid is a bowl which is substantially one-half of an oblate s here and has a series of circular ribs exten( mg circumferentiallv with respect to the vertical axis of thefixture upon the convex exterior of said prismatic element and has a series of radial ribs upon. the concave interior of said element, the light projected therethrough is widely diffused below said fixture. However, as hereinafter described, my invention is not restricted to such materials or specific forms, but my invarious novel features of constructionand arrangement hereinafter more definitely specified.

In said drawing: Fig. I is an elevation of a fixture embodying my invention, partly in section, to show the interior construction arrangement thereof.

Fig. II is an inverted plan view of the structure shown in Fig. I.

In said figures; 1 indicates the ceilin from which the fixture is pendent and Whicfi it isdesigned to illuminate. Said fixture conveniently includes the rosette .2 from 'bars 8, conveniently 1919. Serial No. 313,174.

socket 41 for the electric incandescent lamp 5. Said rosette 2 may be made of any suitable material, but is conveniently formed of pressed sheet metal which may be lowered upon said tube 3 to afford access to electric connections which are ordinarily concealed by said rosette, when the latter is in the normal position shown. Said tube 3 is provided with the collar 5 which limits the position of the conical metallic shell 7 which incloses said socket 1 and which is upheld by the latter in connection with said tube 3. Said shell 7 supports a plurality of hanger three strips of primarily plane sheet metal, which are equally spaced in a circumferential series and which are attached to said shell at their upper ends by the thumb screws 10.

I find it convenient to mount each of said hangers 8 upon the ring 11 which reinforces them and maintains them in circumferentially spaced relation, with plane faces of their upper ends in contact with said ring. As shown in Fig. I, each of said hangers is twisted at its upper end so as to present its plane in radial relation to the axis of the fixture below said ring 11, but the lower portions of said bars are twisted so as to present their lower ends in a plane transverse to said axis, in contact with the upper face of the ring 13 to which each of said hanger bars 8 is rigidly'connected by respective screws 14, Said ring has the annular flange 15 with the internal reinforcement 16 through which extend a circumferential series of said screws 17 which prevent the accidental displacement of the reflector 19 which is supported by said rin 13.

Said reflector 19 is so curved in to the source of light in said lam reflect the major portion of the light diffusely upward upon said ceiling 1, and is conveniently formed of what is known as cased or flashed glass, to wit, glass consisting of two layers of different kinds, which are fused together, for instance; the inner layer 20 may be of the white composition known as opal whereas, the outer layer 21 may be of any desired color, for instance,

amethyst.

relation 5 as to having radial ribs 27 upon is made of colorless glass, it may be made of r rm aterial capable of reflecting a portion of features of my invention,

the light, so as to supplement theillumina tion of said ceiling 1 by the reflector 19. I sometimes find it convenient'to make said element 23 of colored glass and to make either or both of the surfaces thereof smooth instead of corrugated as above described.

Of course, the light reflected upon the ceiling may be colored, for instance, by providing an incandescent bulb 5 which is colored, and various combinations of lighting effects may be produced by changing any of said elements 5, 19 or 23.

It is to be understood that when the screws 10 are withdrawn; the entire structure including the ring 13, reflector 19 and bowl 23 may be bodily removed from the fixture. Whereupon, the reflector 19 may be removed from said ring 13 if the screws 17 are withdrawn.

Therefore, I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein, without departing from the essential as defined in the appended claims.

I claim: r

-1. In a lighting fixture, the combination with a vertical axial support for a lamp;

of an annular reflector, including a translucent colored medium, encircling said support, in such vertical position with respect to said lamp as to reflect the major portion of the light obliquely therefrom; a bowl, of translucent material, separate from said reflector', mounted in concentric relation with said support; and metallic means directly connecting said bowl with said support, in cooperative relation with said lam including a ring extending between sai reflector and bowl, whereby'the major portion of the light from said lamp may be reflected upwardly, bove said lamp, and a minor portionv of said light may be projected downwardly, below said lamp, and a minor portion of said light may be projected through said reflector to display a color.

2. In a lighting fixture, the combination with a source of light; of a light transmitting inclosure for said source, open only at its top, and including acolored cased glass element in its upper portion and a prismatic glass element in its lower portion; both of said elements being arranged to rece1ve and diffusely transmit light from jsa1d.'source; said cased element being arelement in its upper ranged to reflect light upwardly from said source and having its lower edge extending below said source; said prismatic element being smaller in diameter than said cased element; the lower edge of said cased element and the upper edge of said prismatic element terminating in a substantially common plane; and a metal frame ring, in

coaxial relation with said cased and pris-- matic elements and connecting the lower edge of said cased element with the upper edge .of said prismatic element.

3. In a lighting fixture, the combination with a source of light; of a light transmitting inclosure for said source open only at its top, and including a colored cased glass element in its upper portion and a prismatic glass element in its lower portion; both of said elements bein arranged to receive and diflt'usely transmit ight from said source; said cased element being arranged to reflect light upwardly from said source and having 1 below said source; the lower edge of sai cased element and the upper edge of sai prismatic element terminating in a substantially common plane; and a metal frame ring, in coaxial relation with said cased and prismatic elements and connectin the lower edge of said cased element wit the upper edge of said prismatic element.

4. In a lighting fixture, the combination with a source of light; of a light transmitting inclosure for said source, and including a colored cased lass element in its upper portion and a prismatic glass element in its lower portion; both of said elements being arranged to receive and difl'usely transmit ts lower edge extending light fromsaid source; said cased element being arranged to reflect light upwardly from said source and having its lower edge extendingbelow said source; said prismatic element being smaller in diameter than said cased element; and a metal frame ring, in coaxial relation with said cased and prismatic elements and connecting the lower edge of said cased element with the upper edge of said prismatic element.
